[PATCH] D106868: [AMDGPU] Legalize operands of V_ADDC_U32_e32 and friends

[Jay Foad via Phabricator via llvm-commits]

The patch attached to https://bugs.llvm.org/show_bug.cgi?id=51217 tests this. I'm not sure how else to test it, because normally 64-bit add/sub gets selected to a pseudo, which is expanded to add_co/addc by some code in EmitInstrWithCustomInserter which already calls legalizeOperands on the addc.
